What is the working principle of the bucket-wheel stacking and reclaiming machine?

Released:2024-05-13 Author:Shandong Shineng Heavy Industry Technology Co., Ltd. Views:28

The bucket-wheel stacking and reclaiming machine is mainly a crawler-type mechanical device of material handling. It reclaims materials with bucket wheels continuously and stacks continuously with a belt-type conveyor. It is a machine specially used in the bulk yard to load and unload goods. Stacking and reclaiming machines, reclaimers and bucket-wheel stacking and reclaiming machines are collectively called as stacking and reclaiming machines. They become transportation devices necessary for bulk materials, and they can effectively stack and recycle bulk materials. They have features of a large transportation volume and a fast transportation speed, and they are mainly used in various bulk wharves. The bucket-wheel stacking and reclaiming machine is also called as cantilevered stacking and reclaiming machine, which is specially used in bulk yards. The stacking and reclaiming machine is a machine that can be used to excavate and stack coals, mines, sand and other scattered materials. It is not only applicable to power plants, but also suitable for wharves and ports. Most wharves and ports that transport coals and scattered materials adopt bucket-wheel stacking and reclaiming machines. The usage of bucket-wheel stacking and reclaiming machines greatly shorten the stacking time, improve working efficiency and reduce workers' labor intensity.  Domestic designing and manufacturing enterprises that emerged early include Dalian Heavy Industry (formerly known as Dalian Industrial and Mining Vehicle Plant), Harbin Heavy Machine Plant, Beijing Materials Handling Research Institute, etc. 

Bucket wheel stacker reclaimer equipment includes stacker-reclaimer, reclaimer, stacker, mixing reclaimer, mixed stacker and gate stacker-reclaimer, etc. The stacker-reclaimer is a widely used piece of equipment because it is fully functional and able to meet the needs of most conditions. The basic function of the above-mentioned equipment is to stack materials in or remove materials from the stockyard. Among them, the stacker-reclaimer has a stacking function, while the reclaimer and stacker crane only have a reclaiming or stacking function. In addition to the functions of reclaiming and stacking, the mixing reclaimer and the mixing stacker also have the homogenization function to meet the user's requirements for material homogenization.

The bucket wheel of the bucket wheel stacker reclaimer is installed at the front of the belt conveyor and is raised and lowered with the belt conveyor. When the bucket wheel mechanism rotates, and the bucket device rotates to the lower part of the mechanism, the bucket shovels the material into the bucket; When the bucket wheel mechanism continues to rotate to a high position, the material will fall due to its own gravity. At this point, the circular baffle of the bucket wheel directs the material to the receiving trough, where it is conveyed through the belt conveyor to the intermediate downspout. After the material is sent to the middle downpipe, it falls on the tail car belt conveyor, and then conveys to the conveying system through the belt, which is the reclaiming process of the bucket wheel stacker reclaimer. When stacking, the tail car is lifted to the upper part of the belt conveyor, and the material conveying system conveys the material to the head and falls into the material yard through the conveying of the belt conveyor and the reversal of the belt conveyor, which is the stacking process of the bucket wheel stacker and reclaimer. The bucket wheel stacker reclaimer is mainly composed of more than 20 components, such as walking, rotating, tail car, pitching, bucket wheel, door seat, power, counterweight, belt conveyor, electrical room, operation room, water spray and dust removal, hydraulic system, communication cable reel, and various protection devices.


The bucket wheel stacker reclaimer has the dual function of a crane and a conveyor. First of all, it covers the functions of material collection and transportation, which can be operated continuously at the same time; In addition, the energy consumption of the bucket wheel stacker is low due to the low resistance of the belt conveyor used by the bucket wheel stacker to convey materials; In addition, the materials used in the bucket wheel stacker reclaimer are wear-resistant, which also extends the service life of the bucket wheel stacker.
